Buuuut, as of ch.7, we didn't even get one example of a person following all the rules and not screwing up, which kinda waters the concept down for me? Because so far it's not the "demon machine doing demon machine things", or "people can never know what they truly want".
It's just "nobody ever reads the freaking manual", and while it is undeniably true, it's a bit lackluster, given the setting.
